How To Determine The Critical Speed Of Centrifugal Fan ...

2020-8-14 · How is the critical speed of centrifugal fan determined? In this cold winter, everyone wants to work and rest in a warm room instead of working in the cold air. This is a simple and easy thing for us now, but it was a difficult thing half a century ago. First of all, in a warm room, it is very simple to ensure that the temperature does not leak.

Resonance

2015-8-31 · Critical speeds - occurs when a component rotates at its own natural frequency. A "critical speed" is simply when the rotational speed (rpm) coincides with the natural frequency of the rotor (cpm). The tiniest amount of residual unbalance (something that is always present) is enough to cause huge amounts of vibration when rotating at a critical.
